Curious Case of Facial Pain Mimicking Temporomandibular Disorder.

Facial pain is a common but complex complaint, frequently associated with dental issues or temporomandibular disorder (TMD). However, rare aetiologies can complicate conventional diagnoses and treatment approaches. We present a case of a 36-year-old male with persistent jaw pain and restricted mandibular movement, initially managed as a typical TMD case. Conventional treatments yielded no improvement, prompting advanced imaging, which identified an unusual mass within the lateral pterygoid muscle. A surgical excision of the mass was performed, and histopathological examination revealed a rare and unexpected diagnosis. This case highlights the importance of considering uncommon conditions in the differential diagnosis of TMD and facial pain to ensure timely and appropriate therapeutic interventions.

Update on nonoxynol-9 as vaginal spermicide.

Nonoxynol-9 (N-9) is a typical surfactant. For more than 30 years that very property of N-9 has been successfully exploited for its spermicidal action. It is available as an over-the-counter, locally acting vaginal spermicide. The suitability of N-9 as a spermicide is elaborated in this article. The reasons why N-9 may fail as a contraceptive are discussed. In spite of many drawbacks, which are mentioned in the article, N-9 is still often resorted to as a locally acting contraceptive. The review ends with suggestions to alter the molecular structure of N-9 and to adjust the dosages.

Natal teeth in premature dizygotic twin girls.

Presence or eruption of teeth immediately at or after birth is a rarely reported phenomenon. This condition is referred to as natal teeth, neonatal teeth, congenital teeth, fetal teeth, predeciduous teeth and dentitia praecox. The most affected teeth are lower primary central incisors with the incidence of 1:2000 for natal and 1:3500 for neonatal teeth. The aetiology of this anomaly is still not clear, however, attributes have been reported in relation to congenital teeth, multiple factors and some syndromes. The management of such cases depends on clinical characteristics of natal or neonatal teeth, as well as complications that they might cause. The aim of this paper is to discuss a rare case of occurrence of two natal teeth in both premature dizygotic twin female babies with specific emphasis on the literature review related to concerns regarding prevalence, aetiology, clinical characteristics, differential diagnosis, complications and management.
